[v0.9] Fix failed lambda execution crashing coordinator

[Siegrift]

Closes #1565

@amarthadan I wasn't able to build Docker images locally and the CI fails as well (also for the 0.9 branch). I've tried building also on Linux locally, but got an error as well.

I've tried to debug the issue, but I gave that up after a while. I 100% remember testing this and it used to work for me.
I've tested this using the deployer package directly.

I'll take a look.

Ok, found what the issue with Docker builds is, tracked and described in #1585.
